Which of your patients requires TB screening?
Global guidelines and pharmaceutical labeling requirements reinforce that TB testing is critical when evaluating your patient’s treatment options. These treatments extend beyond use in rheumatology, impacting gastroenterology, dermatology and cancer treatment.
In addition to identifying an immediate risk of TB reactivation during primary treatment, TB screening prior to immunotherapy provides you with flexibility as your patient ages and progresses to new medications.

Reduce the risk of future complications
In addition to screening for TB at the onset of immunotherapy, retesting every 1–2 years for patients who have a new or recurring risk factor should be considered. Risk factors include living in or extended travel to an endemic country, TB exposure, or employment in a healthcare or congregate setting. Risk factors such as smoking, substance use disorders, diabetes, etc. should also be considered.
